To (17! tU/LOYH. it may concern:

Be kn u'n that l, ilnosms H. J. KELLY, a citizen of the United States, residing at Edgewood, in the county of Providence and State of lihode Island, have invented a new and useful improvement in Oil Burners, of whichthe following is a specification.

My invention has reference to an improvement in burners such as shown in my United States Patent ilo.v 1,151,188, granted to me August 2:1 1915 and more particularly to an oil burner adapted to burn a gaslormed from kerosene and steam, said oil burner being particularly adapted for use in cooking stoves or ranges.

A further object of my invention is to improve the construction of such an oil burner whereby an intense hot flame is produced, without perceptible odor, at a minimum cost per hour.

Another object of my invention is to simplify the construction oil such an oil burner thereby reducing the cost of manufacturing the burner.

lily invention consists in the peculiar and novel construction of an oil burner, said oil burner having details of construction, as will be more "fully set forth hereinafter and claimed.

Figure l is a vertical longitudinal sec-- tional view through my improved oil burner in place in the fire pit of a cook stove, shown in bro-ken lines.

Figure 2 is a top plan view of the oil burner.

Figure 3 is a vertical transverse sectional view through the burner showing the oil piping and burner tip in full lines and a part of the stove in broken lines.

Figure lis a sectional View similar to Figure 3 showing the water and steam piping in full lines, and

Figure 5 is an enlarged tudinal sectional view tip.

In the drawing 6 indicates my improved oil burner and 7 part'ot a cook stove having the usual fire-pit 3 and grate ledge 9, shown in broken lines. The burner G comprise. a hollow base member 10 having a central opening 11 in its top and supported at each end on transverse bars 12, 12 which in turn detail longithrough the burner are supported at their ends on the grateledge 9. as shown in Figure 3, therebysupportingthe burner 1n the fire-pit oi? the Specification of Letters Patent.

stove. Supported on the base member 10 over the opening 11 is a hollow member 13 having oppositely disposed front and back pipe openings l4, 14, a horizontaljtubular top 15 havinga central semi-circulartransverse heating chamber 16, and 0p ositely disposed open pipe ends 17, 17. 11 each end 17 is adjustably secured a pipe elbow having ascrew-eye 19, the end of which en'-' ters a semi-circular groove in an end 1? and holds the elbow in place. The elbow 18 may be adjusted by the screw eye 19 to throw the flames upwards or over towards the top of the oven. A plate 21 is spaced from and secured to the end of each elbow 18 by a screw or other means. An oil pipe 22 having a valve 23 leads from a source of kerosene oil supply, not shown, to'a vertical pipe 24 through the frontopening 141,

then to a horizontal pipe 25 which extends through the heating chamber 16 to a Vertical pipe 26. T he vertical pipe 26 extends downwards, through the back opening 14 to a horizontal pipe 27 which is connected to a vertical central pipe 28 in the bottom of which is a pet-cock 29 and in the top a burner tip 30. All of these pipes are connected by the usual elbows and fittings, as shown in Figures 3 and 4:. A small pipe 31 leads from a source of water supply, not shown, to a larger pipe 32 which extends upwards through theback opening 14, then over the top of the tubular top 15,- then down through the front opening 14, as shown in Figure at, to a small pipe 33, which extends upwards and is then connected by fittings 341 to the horizontal oil pipe 25, as shown in Figure 3. The tubular burner tip screws into the top of the pipe 28- and has an inner tubular removable member 35 held in place by a perforated screw-cap 36, as shown in Figure 5. A pilot-light pipe 37 is placed so that the light will ignite the gas from the burner tip 30 and is connected to the oil pipe 22, connection not shown.

When in operation the pilot-light is lighted the oil valve opened and kerosene burned on the burner tip 30 until it vaporizes in the pipe 25. The water is then turned on and transformed into steam in the pipe 32, by the heat from the burner. The steam through the pipe 33 enters the pipe 25 and with the vaporized kerosene forms a gas composed of vaporized kerosene and steam. This gas is now burned on the stove, a hollow elbows, a burner tip under oil pipe, a pipe burner tip and is an intense hot flame which strikes the semi-circular outer surface of the heating chamber 16, splits into two flames which come 'out of the space between the ends of the elbows 18, 18 and the plates 21, 21 with a valve, not shown, on the water pipe 31, and the valve 23 on the oil pipe 225the proportionof vaporized oil and steam may be governed atwill.

Having thus described my invention 1 claim as new z i 1. An oil burner having a hollow base with an opening in its top, means for supporting the base on the grate flange o1 a member on the base member and having oppositely disposed pipe ends and a central heating chamber, pipe elbows, means for adjustably securing the pipe elbows to the pipeends, a plate spaced from and secured to the outer end of each pipe elbow, means for adjusting the pipe the heating chant her, an oil pipe through the'heating chamber, means for conveying kerosene to the over the heating chamber, means for conveying water to the pipe over the heating chamber, means for conveying kerosene to the burner tip, means for igniting the kerosene on the burner tip, whereby the heat from the burner tip transforms the kerosene into a vapor and the waterinto steam, means for combining the kerosene member and having oppositely disposed horizontal open pipe ends and a'transverse central heating chamber, a pipe elbow on each pipe end,'means tor adjustably'securing the pipe elbows to the pipe ends in an upwardly turned position, means for adjusting the pipe elbows, a plate spaced from and secured to the upper end of each pipe elbow,

a burner tip under the transverse heating chamber, an oil pipe through'the transverse heating chamber, means for conveying kerosene. to the oil pipe, a curved pipe over the heating chamber, means for conveying water tothe curved-V pipe over the heating chamber, meansfor conveying kerosene to the burner tip, means for igniting the" kerosene on the burner tip, whereby the heat from the burner tip transforms the kerosene into a vapor and the water into steam and means, as described, for combining the kerosene vapor and-steam into a gas, which is then burned on the burner, as described.

In testimony whereof, I have signed my name to this specification.
